Are There Any Unsafe Effects From Long-Term Marijuana Smoking?

While all of the cumulative effects of long-term marijuana smoking are currently unknown, there are studies that have shown reason to be concerned for one’s health. In a study performed by UCLA in California, researchers examined 450 daily pot smokers (non-nicotine users) and found that they had more sick days and doctor’s visits for respiratory issues than others who didn't smoke at all.

It’s hard to determine if smoking marijuana alone can cause cancer, because many people who smoke it also smoke tobacco. Marijuana smoke contains the same cancer-causing chemicals as tobacco, although sometimes in higher concentrations. Some studies have shown that someone who smokes five marijuana joints per day could be consuming the same cancer-causing substances that are found in a whole pack of cigarettes.

Marijuana smokers could develop a daily cough, more phlegm production, more recurrent chest colds and a sharper risk of lung and respiratory infections. Cancer of the respiratory tract and lungs could increase, because the drug contains irritants and carcinogens.

What About How Marijuana Effects Memory?

Neurotransmitters, a key player in overall brain function, are carriers of information between cells known as neurons. THC can affect the interplay of neurotransmitters by altering the strength of some signals and interfering with the normal communication between neurons and brain circuits.

Marijuana abuse during adolescence can produce long-lasting or permanent changes in the function of the brain, particularly in those with a predisposition to psychiatric disorders. Research suggests that recurrent marijuana use during youth can raises the risks of neurosis, a decrease in IQ, as well as changes in the brain that increase a person’s susceptibility to more dangerous illegal drugs.

Outlook

There are many views about marijuana and whether it is good or bad for someone. The amount of THC in marijuana has increased in recent years and in the past it used to be around one to four percent, however, today it is closer to seven percent. Medical experts are concerned the higher THC levels will make it easier for people to become dependent on the drug.
